SummaryProvide an interface for creating families of related objects without specifying their concrete classes.Construct a complex object step by step so the same construction process can create different representations.—
IntentProvide an interface for creating families of related objects without specifying their concrete classes.Separate the construction of a complex object from its final representation.Capture and externalize an object's state so it can be restored to a previous point in time.
Decision factors
ProblemClient code needs to create families of related objects, but hardcoding concrete classes makes the code rigid and hard to swap.Constructing complex objects directly can make required steps, optional values, and validation hard to manage.An object's internal state must be saved and restored later without exposing its implementation details.
Tradeoffs
  • Adds an extra abstraction layer.
  • Can overcomplicate simple object creation.
  • Makes family-wide swapping and consistency much easier.
  • Adds more classes or steps to the construction process.
  • Can be overkill for simple objects.
  • Improves clarity when object construction is complex or incremental.
  • Snapshots can consume memory if many states are stored.
  • Care must be taken to keep mementos immutable and hidden from outside code.

Integration notesAbstract Factory is especially useful when your app must produce matching sets of related objects for a theme, provider, platform, or pipeline.Builder is most useful when construction must happen in controlled steps and the final object has many optional or ordered parts.Memento is useful for undo/redo, checkpoints, draft recovery, and any workflow where state history matters.
